The Elements of Weather

Understanding Basic Concepts
- explain the difference between weather and climate and the factors that influence both of these systems
- identify patterns in air movement
- identify the effects of air pressure


What is Weather?

http://oncampus.richmond.edu/academics/education/projects/webunits/weather/how.html

1. Define weather.The WEATHER is the condition of the atmosphere at a particular time and place.
2. What four factors affect weather-The air,the sun, water, and the earth's movement



Weather vs Climate

3. What is the difference between climate and weather?Climate is what you expect; Weather is what you get

Air Pressure

Measuring the Weather

Developing Skills of Inquiry, Design and Communication
- design, construct, and test a variety of weather instruments
- use appropriate vocabulary, including correct science and technology terminology, in describing their investigations and observations


The following web site describes some of the instruments meteorologists use to collect data about the weather.

Use the information to complete the chart.
The source of this information is American so you may have to determine the equivalent metric unit to record in the chart.

Clouds

Understanding Basic Concepts
- explain the formation of clouds and the effects of different cloud formations on weather and climate


Use this web site to answer the following questions.
http://oncampus.richmond.edu/academics/education/projects/webunits/weather/clouds.html

1. What are clouds?Clouds are a visible mist of billions of water and ice particles floating in the sky.
2. Explain how clouds form.Clouds form when air cools below its saturation point and causes water vapor to condense into tiny water droplets.
3. What are the 3 "families" of clouds and what do their Latin names mean?There are three families of clouds: cirrus, cumulus, and stratus.
4. Follow the links to learn about each type of cloud and then complete the table on the next page.
To help you identify clouds, download, print and construct the following "Cloud Key".

Forecasting

Understanding Basic Concepts
-recognize large-scale and local weather systems
- predict local weather patterns using data from their own observations of weather and from weather reports
- identify patterns in air movement


Read the details at http://weathereye.kgan.com/cadet/forecast/camp.html and follow the links.
The following questions and organizers will help you keep track of the crucial information you’ll need.

Cloud Type
Description
Possible Weather
cirrus
Cirrus" in latin means curl and these clouds are named because they resemble wisps of curly hair.
RAIN
altocumulus
Altocumulus clouds consist of a thin sheet of white or gray clouds that are broken into bands, blobs, rolls or waves.
RAIN OR SNOW
nimbostratus
leads to rain,snow,gray skies, and low pressure
RAIN AND SNOW
cumulus
puffy clouds,low altitude,cool,moist,and they cause rain
RAIN
cumulonimbus
puffy clouds, dark clouds, rain, stroms, rain showers,snow,hail,or thunderstorms

Warm and Cold Fronts

Understanding Basic Concepts
- explain the difference between warm and cold fronts and the factors that influence both of these systems
- identify types of weather associated with each front

http://www.classzone.com/books/earth_science/terc/content/visualizations/es2002/es2002page01.cfm?chapter_no=visualization


Write the capital letter A or B at the end each sentence.

A = Cold Front B = Warm Front

1. Cool air mass - warm air mass moves inB.
2. Warm air mass - cool air mass moves in.A
3. Brings gentle rains that may last for hours or days.B
4. Strong winds are formed followed by heavy rain, crashing
thunder, and flashing lightning.A
5. When the front passes, the temperature warms up and it
becomes humid.B
6. When the front passes, the weather turns cooler.A
7. Farmer Brown prefers this type of front.B
8. Usually happens and is over with quickly.B
